I am looking into purchasing an iMAC this summer. I have heard rave reviews about the iPHOTO program on the laptop. I know I am new to photography, but I am determined to learn HDR photography. Its the most insane photography I've ever seen and apparently the iPHOTO is capable of giving you those true colors to create HDR photography. And just in general I'd like to have to a computer that has a good photoshop program so that I can become more capable and understanding in photoshop.
